Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Imported malaria in the mainland France from 1996 to 2016 : representativeness, assessment of the French National Reference Centre for malaria network and imported malaria risk modeling
No full textLa recrudescence des voyageurs vers les zones d'endémie palustre et le nombre élevé de cas importés ont accentué la nécessité de mettre en place une surveillance épidémiologique du paludisme. En dépit des mesures de prévention visant à réduire le risque d'infection chez les voyageurs, le nombre de cas de paludisme demeure élevé en France. Dans le cadre de la surveillance épidémiologique du paludisme, les cas rapportés en France pendant la période 1996-2016 ont été analysés et le système d'information et de surveillance du paludisme a été évalué. Une analyse des tendances épidémiologiques met en évidence les différents changements sur les caractéristiques épidémiologiques du paludisme en France au cours de deux dernières décennies. Une collaboration de recherche a été mise en place avec Santé publique France (SPF), l'Institut français de surveillance de la santé publique pour l’utilisation des données du registre national des causes de décès en médecine (CépiDc) et du Programme de Médicalisation du Système d’Information (PMSI) pour l’estimation du nombre de décès liés au paludisme en France. Nous avons utilisé les méthodes de capture-recapture à deux sources et les modèles log-linéaires pour estimer le nombre total de décès. Par ailleurs, de façon rétrospective, nous avons utilisé les données de trois enquêtes exhaustives sur le contrôle national de qualité en parasitologie pour estimer le nombre total des cas de paludisme en France. Il est ressorti de ce travail, que le système de surveillance du CNR du paludisme était stable au cours de la période d'étude, avec 85% des cas de paludisme rapportés au CNR du paludisme par 66 centres participants ayant déclaré constamment leurs cas au cours de la période d’étude, la sensibilité pour les décès était seulement de 38%, inférieure à celle des cas (52%). Sur le plan épidémiologique, les changements les plus frappants ont été l'augmentation de la proportion de cas de paludisme chez les individus d’origine africaine (de 53,5% en 1996 à 83,4% en 2016, la plupart des voyageurs qui visitent de la famille et des amis (VFR), 79,6% en 2016), une augmentation de l'âge médian des patients de +8 ans (africains, +10 ans et européens, +7 ans) et le doublement de la proportion de cas graves. En conclusion, ces changements dans les caractéristiques épidémiologiques des individus atteints de paludisme importé en France métropolitaine questionnent sur la stratégie actuelle de prévention pour les voyageurs. En termes de perspective, l’utilisation des enquêtes exhaustives et des méthodes de capture-recapture pourraient être des alternatives à des études longues et coûteuses permettant une évaluation quantitative des systèmes de surveillance, ainsi qu’une harmonisation des indicateurs de surveillance des maladies infectieuses en Europe.Increase in travellers to malaria-endemic areas and the higher incidence of imported malaria cases have accentuated the need to set up an early warning system for malaria control. Despite prevention measures aimed at reducing the risk of infection among travellers, the number of malaria cases remains high in France. In that case, malaria cases reported in France from 1996 through 2016 were analyzed and the malaria information and surveillance system was evaluated. Interestingly, collaboration has been set up with Santé Publique France (SPF) for the use of data from the French National Registry on medical causes of death (CépiDc) and the French national hospital discharge database (PMSI) in regards to estimating the number of malaria-related deaths in France. This was done by using a two-source capture-recapture methods and log-linear models. In addition, retrospectively, we used the data from three exhaustive surveys based on questionnaire sent to all the medical laboratories belonging to the national quality control in parasitology in collaboration with the national Agency for the safety of Medical Products (ANSM) to estimate the total number of malaria cases in France. Then, we described trends in epidemiologic characteristic of imported malaria in France from 1996 to 2016. It emerged from this work that our surveillance system was stable during the study period, with 85% of malaria cases reported by 66 of participating centres having regularly declared their cases during the study period, the sensitivity for death was only 38%, poor compared to that of cases (52%). At the epidemiological level, the most striking changes were the increase in the proportion of malaria cases among African individuals (from 53.5% in 1996 to 83.4% in 2016, most of them African VFRs, to 79.6% in 2016), the 8-year increase of the median age of the patients (African, 10 years and European, 7 years) and the doubling in the proportion of severe cases. What we have learned from this study is that these changes in the epidemiological characteristics of individuals suffering from malaria should imply a strengthening of malaria preventive strategy to alleviate the burden of the disease among travellers in France. In the last two decades, substantial progress has been made to enhance malaria surveillance in France by providing appropriate diagnostics and treatments, enhancing the French malaria surveillance system. In this situation, the excellent quality of the data, the sensibility of the captures, the stability of the network, and the large contribution of the correspondents to malaria network are useful as they allow validating results on a large scale. In perspective, the use of national surveys and capture-recapture methods could be alternatives to long and costly studies allowing a quantitative evaluation of surveillance systems and harmonisation of indicators for infectious diseases control in Europe. Furthermore, reducing the cost of malaria prophylaxis and national preventive campaign toward population at risk are essential to continue the downward trend of imported malaria incidence in France

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
